high-intensity light for microscopes. Use the rotary dimmer switch to
control the halogen light source for a continuous range of subdued
or concentrated lighting. The Z-LITE is available in the following
congurations:

3200°K. Forced air cooling prolongs the lamp life. The EJA bulb can be
used as a replacement lamp. When you open the front panel, a safety
switch automatically shuts o the power.

OPERATING INSTRUCTIONS
1. Plug the illuminator’s AC power cord into a grounded receptacle.
2. Turn the rotary dimmer knob (large black knob on the front panel) in
a clockwise direction to increase the light intensity. A click indicates
that the power is ON. When you rotate the knob to its extreme clock-
wise position, the light is at its brightest. Rotating the knob counter-
clockwise decreases the intensity of the light and also shuts o the
power.
Using Light Guides
The metal light guide port on the face of the Z-LITE (bottom left) has
an inside diameter of 5/8” to accommodate ber light guides. See
ACCESSORIES. Insert the desired light guide into the connection port and
tighten the knurled light guide knobs to hold the guide rmly.
Replacing the Bulb
1. Shut o the power and remove
the AC power cord from the outlet.
Although the power is automatically
shut o by a safety switch when the
front panel is opened, removing the
AC cord is a precautionary measure.
2. Loosen the knurled case knob on
the top of the case until the front panel opens.
3. The bulb release lever is located on the left side of the bulb. Push this
lever upward. The lever pushes the bulb which slides forward out of
the cradle.
4. Gently pull the socket away from the back of the bulb.
5. To insert a new bulb, push the bulb release lever down into its origi-
nal position. Align the two pins on the lamp with the two holes in the
socket. Firmly press the bulb into the socket until the pins are fully
seated. Then, push the bulb back until its cradle.
6. Close the front panel, re-tighten the knurled case knob, plug the AC
power cord into the power outlet.
Changing the Fuse
This unit is equipped with a fuse. The fuse will blow if a problem occurs. If
this happens, wait until the lamp cools down before attempting to replace
the fuse. If the fuse continues to blow, there is a short and the problem
must be xed by a qualied technician. To change the fuse:
1. Insert a small, at-head screwdriver
into the recess on top of the fuse
housing that is located on the back
of the unit. The fuse casing pops
out.
2. Remove the casing and the fuse.
3. Position a new fuse in the casing and reinstall the casing.
